My idea to stop sideways drift while angling the blade on bulldozers was to make the tracks so they could be tilted, kind of how a grader tilts its wheels to stop that nonsense. Obviously this is a MUCH better way.

Equally, I can see putting carbide teeth on the third track chain so that in stumping it would just shred the stump instead of pushing the stump over and having to push it all the way across the clearing. I am not a huge fan of stump grinding in land clearing anyway because what is left often rots down leaving gaps and holes that livestock can step into and break ankles and legs, but burning stumps and pushing into ravines is not always possible. Obviously pushing across a new field can mean really long pushes!

It is an interesting concept, but like anything today, looks EXPENSIVE with the separate engine and hydraulic system driving it. I bet an enterprising person though could cobble together a third track assembly vertically and rig up an engine to power it.

I have no intention of traveling to my grave in a well manicured body; instead I am going to slide into heaven with a big power turn, totally wore out with busted knuckles, jump off my dozer loudly yelling, Woo Hoo, another Shepard has just arrived!

For clearing, what you want is one of those huge selfpowered flails hooked onto the blade frame of a D8. You know the ones the park service uses to blast trails thru the forest. The power companies love them as well. They take trees and make them into a carpet of mulch.

We have a rental company here that has them for rent, but they are pretty pricey. $10,000 a month (28 days or 160 hours), but also requires insurance before renting. There's is mounted to an excavator though. I thought about renting it, but $10,000 for 160 hours is a lot of money!

I looked at some at a farm and logging show and cannot see why a homemade version cannot be made. They looked pretty simple, just a rotating bar holding carbide teeth counter-rotating against a fixed bar. Mechanical or hydraulic power via an engine could easily get a person there.
